What is the percent increase from 8 to 10?

You need these:

AMOUNT OF INCREASE = NEW QUANTITY - OLD QUANTITY  

                       AMOUNT OF INCREASE
FRACTION of INCREASE = ——————————————————
                          OLD QUANTITY

DECIMAL OF INCREASE = FRACTION OF INCREASE CHANGED TO A DECIMAL

PERCENT OF INCREASE = DECIMAL OF INCREASE CHANGED TO A PERCENT

--------------------------------------------------------

In your problem, OLD QUANTITY = 8, NEW QUANTITY = 10

AMOUNT OF INCREASE = NEW QUANTITY - OLD QUANTITY  = 10 - 8 = 2

                       AMOUNT OF INCREASE    2
FRACTION of INCREASE = —————————————————— = ——— 
                          OLD QUANTITY       8

DECIMAL OF INCREASE = FRACTION OF INCREASE CHANGED TO A DECIMAL
              
              .25
           8)2.00
             1 6
               40
               40 so decimal of increase = .25

PERCENT OF INCREASE = DECIMAL OF INCREASE CHANGED TO A PERCENT

Percent of Increase = .25 changed to a percent = 25%
